Definition
The lawful money issued under authority of the federal government of the United States and recognized as legal tender for the payment of debts, public and private. The term encompasses the full body of federally authorized monetary instruments — including coin, treasury notes, and bank notes issued under congressional authority — that serve as the official medium of exchange within the United States.
The concept rests on the constitutional power of Congress to coin money and regulate the value thereof (U.S. Const. art. I, § 8), and was given concrete institutional form through the National Currency Act of 1863 and the National Bank Act of 1864, which established a uniform system of nationally chartered banks authorized to issue currency backed by U.S. government bonds.

Common Confusion
The term is sometimes conflated with "legal tender," but the two are not identical. Legal tender is a narrower designation — it identifies which instruments a creditor is legally obligated to accept in satisfaction of a debt. Not every form of national currency has carried legal tender status at all times in U.S. history; national bank notes, for instance, were widely used as currency but did not always carry full legal tender status. Researchers encountering the term in historical sources should not assume legal tender status without confirming the specific instrument and time period.
The term also should not be confused with "federal reserve notes," which are the dominant form of U.S. paper currency today. Federal Reserve notes emerged from the Federal Reserve Act of 1913 and largely replaced the earlier national bank note system over time.

Why It Matters in Research
This term appears most frequently in indictment practice and criminal pleading contexts in the late nineteenth century — which is precisely the context in which Rapalje & Lawrence flag it. Courts required that indictments for counterfeiting, forgery, or offenses involving money specifically identify the instrument as a "national currency of the United States" rather than using generic or imprecise language. Failure to allege the precise character of the currency could be fatal to an indictment, as illustrated by the Virginia authority cited in Rapalje & Lawrence (25 Gratt. 965).
Researchers working with criminal pleading materials from the 1860s–1900s should be alert to this precision requirement. The phrase was a term of art in indictment drafting, not merely a descriptive label. When searching historical reporters for currency-related criminal cases, variant phrasings ("notes of the national currency," "bills of the national currency of the United States") may appear and reflect the same pleading requirement.
The broader monetary law context also matters: U.S. currency law underwent substantial transformation across the Civil War era, Reconstruction, and the populist monetary debates of the 1880s–1890s. Sources from these periods use overlapping and sometimes inconsistent terminology — "greenbacks," "United States notes," "national bank notes," "coin," and "lawful money" each carry distinct legal meanings that may not be immediately apparent from the text alone.

Historical Dictionary Support
Rapalje & Lawrence's entry under this heading is notably sparse, consisting almost entirely of a redirect to a Virginia case citation and a parallel entry on villeins (nativi conventionarii), which reflects nothing more than an alphabetical accident of the dictionary's organization. The entry does not define the term substantively, but its placement confirms that the phrase was recognized as a discrete legal term requiring specificity in criminal pleading by the time of the dictionary's 1883 publication.
The citation to 25 Gratt. (Va.) 965 — a Virginia Supreme Court of Appeals decision — signals that the precise language of indictments charging offenses against the currency was actively litigated, and that courts were enforcing strict pleading standards. This is consistent with the broader common law tradition of requiring exact identification of the instrument in fraud and counterfeiting indictments.
Historical dictionaries of the period generally do not devote sustained treatment to "national currency" as a standalone legal concept; coverage tends to appear instead under "legal tender," "money," or "bank notes." This gap means that researchers relying solely on period legal dictionaries will likely need to supplement with treatises on criminal pleading and monetary law statutes.

Jurisdictional Note
The substance of what constitutes the national currency is federal law by definition. However, state courts — including Virginia, as Rapalje & Lawrence's citation shows — played a significant role in developing the pleading rules governing how currency must be alleged in indictments, since much criminal prosecution occurred at the state level even for offenses touching federal instruments.
